| Abstract: | The basic principles of the one-dimension noise sub-space algorithm are introduced in detail. The performance of the one-dimension noise sub-space algorithm based on the correlation matrix constructed by reusing the conjugating data being rearranged is analyzed. This modified algorithm can improve the performances of the coherent signal sources DOA estimation obviously when the snapshot number is limited. The computer simulation results show that the modified algorithm is effective. |
